FORD lists this plug blanking threaded under number 6l2z7h398e.
A cap that vents and a cap that does not are visually similar, and swapping them gives a fault code or a pressure leak rather than a fit problem.
The part number is the thing to verify. Where the old part carries no legible number, a VIN and a photograph are enough for us to identify it.
